BMW has released another teaser video of the 1-Series M Coupe. Earlier this month BMW had released a cockpit video of the 1-Series M Coupe driving around the Ascari race track in Spain. It was reported that the car will be unveiled in December, before its world premiere at the 2011 North American International Auto Show.

Features that we can clearly make out from the latest video are the new wheels with that typical BBS-like design, quad exhaust tailpipes typical of modern BMW M cars, and of course the car also gets its own M styling.

As previous reports suggest, power will likely be provided by a twin-turbo N54 inline-six with at least 350 PS (257 kW / 345 bhp). It will be mated exclusively to a six-speed manual gearbox, which should allow the vehicle to accelerate from 0-60 mph in approximately 4.5 seconds.
